Davies won bronze in the shot put in London and said he would now focus on winning gold in that event in three years’ time.

“I’m lucky that I still have one event,” he added.

“There are other athletes who don’t have any events at all. I’ll be going for gold in the shot, but it’s devastating I won’t be able to defend my Paralympic discus title.”

The IPC said the split of para-athletics events would be 95 for men and 82 for women – a 22% increase in the number of medal events for women from London 2012.

The number of medal events for athletes with high-support needs will also increase by 22%, from 45 to 55.

Yorkshire’s Hannah Cockcroft, who added the World sprint-double to her Paralympic double last week, will not be able to defend her T34 200m title after it was taken off the schedule and replaced by the 800m.

There was more positive news for Northumberland’s Stephen Miller, who has won three Paralympic golds in the F32/F51 club, but missed out on a medal in London.
